I have gigabit internet from AT&T - $70 a month. On my best computer I routinely get 900Mbps+/900Mbps+. No data caps, no extra fees.
Even in the few areas where Comcast does offer 1Gbps they still only have 35Mbps up stream. It's the cable companies that are being left behind by fiber deployments.
Verizon stopped deploying FIOS to new cities in 2010 and entirely in 2015. Since then, they've begun building out in Boston, but future plans are unclear. AT&T has been deploying new fiber, but that was a condition for them to acquire DirecTV. It's a long way from being an option for most Americans.
